php – Twitter API无法托管[在localhost上正常工作]

<?php
// $lat = $_GET['lat'];
$lat = 26.511740;

// $long = $_GET['long'];
$long = 80.234973;

require_once("twitteroauth/twitteroauth.php"); //Path to twitteroauth library

$notweets = 100;

$consumerkey = "XXXX";
$consumersecret = "XXXX";
$accesstoken = "XXXX-XXXX";
$accesstokensecret = "XXXX"; 

function getConnectionWithAccessToken($cons_key,$cons_secret,$oauth_token,$oauth_token_secret) {
  $connection = new TwitterOAuth($cons_key,$oauth_token_secret);
  return $connection;
} 

$connection = getConnectionWithAccessToken($consumerkey,$consumersecret,$accesstoken,$accesstokensecret);

$tweets = $connection->get("https://api.twitter.com/1.1/search/tweets.json?geocode=".$lat.",".$long.",5mi&result_type=recent&count=".$notweets);

// echo $tweets;
echo json_encode($tweets);
?>

我正在使用Wamp服务器(PHP V5.5.12),我的代码工作正常.但是当我在一些免费托管网站(我尝试过hostinger.in和000webhost.com)上托管我的应用程序时,这个脚本失败了,只打印’null’.

请帮我解决这个问题.

提前致谢.
